The prolific rocker will also host a special performance from the recently reunited alt-rockers Failure, as Spin reports. Their set is a much-appreciated gift to Keenan, who said in a statement, “This was the perfect opportunity to tick off one of my bucket list items in the form of a Failure reunion. What better birthday present could one ever hope for?”

Tickets for Keenan’s “Cinquanta” gig will go on sale on Friday, December 6th at 10 a.m. PST on Ticketmaster. Prices have not yet been revealed. A VIP package that includes preferred seating and commemorative merchandise will be available starting the day before at 10 a.m. PST.

Keenan’s kept quite busy this fall with both Puscifer and A Perfect Circle. The latter just released a new box set, A Perfect Circle Live: Featuring Stone and Echo and a greatest-hits compilation, Three Sixty. Back in August, Puscifer released a new remix record, All Re-Mixed Up, and they just put out a live DVD, What Is…. The DVD finds the band mixing comedic elements and peculiar characters into their live set, and also includes a documentary that Keenan recently told Rolling Stone will help fans make sense of everything. “There’s a lot of stuff that comes up in the show that if you don’t know anything about the other characters, it doesn’t really make any sense,” he said. “But I think we’re setting up the DVD so you can either skip that or include that. And [Andy] Kaufman is definitely a huge influence. Just his alter egos and he had a very pure, twisted sense of comedy.”

Keenan also spoke to Rolling Stone about the “very tedious process” of putting together Tool’s next record. The follow-up to 2006’s 10,000 Daysis expected to come out next year, though Keenan mentioned that his bandmates, who typically write the music before sending it to him, have a tendency to constantly revise and nitpick. “In some ways, they are bigger perfectionists,” he said. “But you can only help support their talent so long. They don’t have to go through it 700 times. They can trust that first thought. But that’s their process, so you gotta let them do it.”
